Application filed May 12, 1916. Serial No. 97,191.

To all wkomc't may concern:

Be it known that I, ALFREDO OVALLE (VIcUfiA) the name Vicufia being my mothers family name, a citizen of the Republic of Chile, and resident of Santiago, Chile, temporarily residing at the Hotel McAlpin, borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Raising Liquids, of which the following is a specification.

This invention has reference to means for raising liquids, the object being to produce an apparatus or pump in which liquid can be raised to any height with the assistance of atmospheric pressure, the column of water acting as a piston, and without any power other than that necessary to produce the desired results.

It is well known that the atmospheric pressure acting inside a vertical tube of any diameter exhausted of air and full of water, having its upper part hermetically closed and its bottom part opening inside a well, is equal to the weight of a column of water of the height of ten metersthirty three centimeters.

The atmospheric pressure can force up water in a vertical tube exhausted of air, to the height already stated.

Then, as a consequence of this principle,

any tube full of water under the same conditions, that is of a shorter length than 10 meters 33 centimeters, has in its interior a latent atmospheric force equal in proportion to the atmospheric pressure, that has not been used according to the shorter length of this tube, and consequently the water in the closed top end of this tube is all the time endeavoring to rise higher.

If this latent force of which I am speaking could profitably take out to the open air the water from the tube without losing the vacuum inside the tube, and of Course without dropping its column of water, an immense advantage could be obtained in raising water.

This is accomplished with my invention which will be fully described hereinafter and the features of novelty of which will be pointed out in the appended claim.

In order that the invention may be clearly understood and easily carried into practical efiect I have appended the accompanying sheet of drawings in which I have illustrated an example of my apparatus for raising liquids with the tubes'placed in a vertical l1ne. c 7

' Thefigure is a broken part sectional elevation showing my apparatus with two tubes working on the balance principle for raising and ejecting liquids alternately from each tube to a height less than the pressure of one atmosphere.

Referring tothe drawing, A is the tank or any body of water. B and B the tubes which raise the water, the lower ends of said tubes being submerged in the water in tank A and being each preferably provided with a valve 6 A valve 6 is also provided in the upper end of these tubes, D is a small tank or vessel containing water fixed to the upper ends of tubes B, B the valve 6 in this end of said tubes being always submerged in the water contained in this vessel. E is a tank, supported by the frame of the apparatus, into which the water from the tubes B, B is discharged. F is a balanced lever, supported on its axle by the frame of the apparatus. The ends of this balanced lever are forked to span the tubes B, B and in each of these forked ends a pulley f travels, said pulley being mounted on collars f secured to tubes B, B Fixed by collar 6* to tube B is a connecting rod f eccentrically secured to disk f mounted on a shaft driven by gear wheels 7 from pulleys 7". It will be seen that when motion is imparted to connecting rod that tube B will ascend and oscillate balanced lever F causing tube B to descend and discharge its water into tank E without droppingthe column of water contained therein. The two tubes being full of water and of the same weight act as a counterbalance thereby assisting in the movement of said tubes. As tube B ascends its lever valve 6 opens and the upper valve 6 remains closed the water from tank F continuing to ascend in this tube until it reaches the limit of its stroke but as tube B descends its upper valve 5 opens and ejects the water without dropping the column of water contained therein. Instead of using two tubes counterbalanced I may employ one tube only, the weight of the tube and water being counterbalanced by a spring. The lower ends of tubes B, B are guided by the collars b fixed to the frame of the apparatus. Guides may also be provided at the upper ends of said tubes.

' and in What manner the same is to be per.-

formed I declare that What I claim is An apparatus of the kind described comprising a tank containing a supply of Water,

a pair of parallel tubes each having one end submerged in the Water in said tank, a receptacle carried by each tube at its other end, said receptacles each containing a supply of Water in which said other ends of said tubes are submerged, siphon outlets carried by each receptacle, valves controlling the oppo-' site ends of said tubes and means for reciprocatingsaid tubes relatively to said tank.

In testimony whereof I have hereunto set my hand.
